Mill Capacity Calculations

There are a large number of formulae for the calculation of the capacity of a milling tandem. Hugot gives the following formula:

A = 0.8 c·n·√N·(1-0.06·n·D)·L·D²/f

where

• c
  is a factor dependent on the cane preparation equipment,
  c
  = 1.3 if the tandem is preceded by a shredder
• n
  is the mill speed in rev/min
• N
  is the number of rollers in the tandem
• L
  is the length of the roll in metres
• D
  is the mean diameter of the rollers in metres
• f
  is the fibre percent cane
